And in the earth are pieces neighboring one another, from them what is good it grows what benefits the people, and from them is brackish salty not growing anything, and in the good earth are gardens of grapes, and He made therein different crops and palm trees joined in one place of growth, and not joined therein, all that in one soil, and drinking from one water, but it differs in the fruits and the size and the taste and other than that, for this is sweet and this is sour, and some of them are better than others in the eating, indeed in that are surely signs for whoever had a heart that understands from Allah the Exalted His command and His prohibition.
